1. Log in to the Abiquo server as the system administrator

2. Create a folder to store the configuration

   Code Block
   mkdir /opt/abiquo/config/saml

3. Download the federation metadata XML file for your configuration. This may be from a link like:
   https://login.microsoftonline.com/<TenantDomainName>/FederationMetadata/2007-06/FederationMetadata.xml
   See https://learn.microsoft.com/en-us/azure/active-directory/azuread-dev/azure-ad-federation-metadata#federation-metadata-endpoints

4. Create a metadata file for the identity provider, for example, at /opt/abiquo/config/saml/idp_metadata.xml and edit this file.

5. Open the metadata XML file, and copy the EntityDescriptor bracket with only the IDPSSODescriptor bracket inside it. Paste it in your metadata file for the entity provider.
   It should look something like this but with different values for your identity provider.

   Code Block
   <?xml version="1.0" encoding="utf-8"?> <EntityDescriptor ID="_d75abe92_blah" entityID="https://sts.windows.net/d123456-blah/" xmlns="urn:oasis:names:tc:SAML:2.0:metadata"> <IDPSSODescriptor protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol"> ... </IDPSSODescriptor> </EntityDescriptor>

   1. The entityID should be the value from your file. It may be something like this: https://sts.windows.net/d12345678-123e-49321-1234-1234abcd567890/

   2. The EntityDescriptor ID should also be the value from your file.

6. Edit /var/www/html/ui/config/client-config-custom.json and add the following configuration to allow SAML login.

   Code Block
   "client.login.modules": [ { "label": "Basic Auth", "description": "Basic Auth login", "templateUrl": "modules/login/authenticationmodules/basicauthentication/partials/basicauthenticationloginview.html", "cookieName": "" }, { "label": "SAML", "description": "SAML login", "templateUrl": "modules/login/authenticationmodules/saml/partials/samlloginview.html", "cookieName": "ABQSAMLTOKENS" } ]

7. Edit /opt/abiquo/config/abiquo.properties and configure the following properties.
   

   Code Block

   abiquo.auth.module = saml abiquo.saml.mode = multi abiquo.login.samesite = strict # Mandatory property to control the maximum time in seconds that users can use # SAML single sign-on after their initial authentication with the IDP. # The default represents 24 days. abiquo.saml.authentication.maxage = 2073600 abiquo.saml.redirect.endpoint = https://ABIQUO_FQDN/ui abiquo.saml.redirect.error.endpoint = https://ABQIUO_FQDN/ui/?error abiquo.saml.keys.keystore.path = /opt/abiquo/config/saml/MY_SAML_KEYSTORE abiquo.saml.keys.keystore.password = MY_SAML_KEYSTORE_PASSWORD abiquo.saml.keys.signing.alias = MY_SAML_APP_NAME abiquo.saml.keys.signing.password = MY_SAML_KEY_PASSWORD abiquo.saml.keys.encryption.alias = MY_SAML_APP abiquo.saml.keys.encryption.password = MY_SAML_KEY_PASSWORD abiquo.saml.keys.metadata.sign = false abiquo.saml.binding = urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect abiquo.saml.metadata.mode = generated #abiquo.saml.metadata.serviceprovider.path = /opt/abiquo/config/saml/sp_metadata.xml abiquo.saml.metadata.identityprovider.default.id = MY_ENTITY_ID # For >1 IDPs, add commas between XML paths abiquo.saml.metadata.identityprovider.path = /opt/abiquo/config/saml/idp_metadata.xml # For >1 IDPs, add commas between pairs of values abiquo.saml.metadata.identityprovider.userdomain.map = myorg.onmicrosoft.com=MY_ENTITY_ID # Set the claim names we have set up before in Azure AD abiquo.saml.attributes.role.claim = abq-role abiquo.saml.attributes.enterprise.claims = abq-enterprise abiquo.saml.attributes.user.id.claim = http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name abiquo.saml.attributes.user.firstname.claim = http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname abiquo.saml.attributes.user.lastname.claim = http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname abiquo.saml.attributes.user.email.claim = http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress

   1. The #abiquo.saml.metadata.serviceprovider.path property should be commented out because first you can generate the metadata and later provide it with the file saved at this path

   2. Replace the following values with the values for your environment:

      1. ABIQUO_FQDN

      2. MY_SAML_KEYSTORE

      3. MY_SAML_KEYSTORE_PASSWORD

      4. MY_SAML_APP_NAME

      5. MY_SAML_KEY_PASSWORD

      6. MY_SAML_APP

      7. MY_SAML_KEY_PASSWORD

      8. MY_ENTITY_ID: you can get this from the Azure federation XML. It may be something like https://sts.windows.net/d12345678-123e-49321-1234-1234abcd567890/ 

8. Create a keystore with the above keystore values.

   Code Block
   cd /opt/abiquo/config/saml keytool -genkey -v -keystore MY_SAML_KEYSTORE -storepass MY_SAML_KEYSTORE_PASSWORD -alias MY_SAML_APP_NAME -keypass MY_SAML_KEY_PASSWORD -keyalg RSA -keysize 2048 -validity 10000

   (In our test system we are used the one value for the signing and encryption password as MY_SAML_KEY_PASSWORD)

9. Restart the Abiquo API

10. Check that the API works and has started successfully by logging in to Abiquo with basic auth as admin

...

Add multiple identity providers for SAML

...

About enterprise and role binding

The Abiquo API can get the user’s SAML attributes, select the correct role, and assign it to the You can configure more than one identity provider for SAML. With the configuration, when the user enters their email address to log in, Abiquo will select the IdP based on its domain name, or it will use the default IdP. 

Abiquo still uses the same IdP configuration for all providers, for example, it will search for the same abq-role attribute to match an Abiquo role.

To configure an existing SAML integration with more IdPs, do these steps on the Abiquo Server:

1. Save the metadata for the new IdPs, as for the first IdP

2. For the default IdP, edit the metadata and set the Default attribute

3. Edit the abiquo.properties file to make these changes:

   1. Add the paths to the metadata of the new IdPs as a comma separated list to the abiquo.saml.metadata.identityprovider.path property

   2. To set the default IdP, add the new abiquo.saml.metadata.identityprovider.default.id property

   3. To map the user email domains to IdPs, set the new abiquo.saml.metadata.identityprovider.userdomain.map property with a comma separated list of keys and values. For example:

      Code Block
      abiquo.saml.metadata.identityprovider.userdomain.map = example.com=https://sts.example.com/ffff2108-833e-4940-87e6-3d39ce9adb70/,abiquo.com=https://idp.example.com

      Do not use a comma , in a key or a value
      Do not use use an equals sign = in the key

4. Share the Abiquo SP data with the new IdPs

5. On the UI server, edit the client-config-custom.json file and change the client.login.module property from SAML to SAML + user.
   For more details, see the examples in client-config-default.json file.

For this feature, there is a new /saml/idp endpoint in the Abiquo API where the UI will send a GET request with the user domain. This endpoint will return a redirect to the usual /saml/login endpoint with the appropriate IdP. Then the login will continue as for a single IdP.

About enterprise and role binding

The Abiquo API can get the user’s SAML attributes, select the correct role, and assign it to the user. This is called enterprise and role binding.

...

...

For SAML, you can configure the following UI configuration properties in client-config-custom.json. See Configure Abiquo UI for more details.
